Does Flex Seal cover rust?

It takes less time to cover a surface spraying Flex Seal because of its thicker consistency that sprays out liquid and dries to a flexible rubberized coating. Flex Seal, on the other hand, not only covers up the rust it also prevents it from growing, never to be seen again!

That’s not what Flex Seal does. Rust will continue to spread unless you eliminate the rust. The Flex Seal may slow it for a time, but the rust will continue. If you have large areas of rust, fix it correctly by eliminating the rust, either though grinding and chemical treatment or replacing the panel.

Furthermore, what does Flex Seal not stick to? Flex Seal will adhere to most any surface such as: wood, metal, tile, concrete, masonry, fabric, glass, plastic, aluminum, porcelain, dry wall, rubber, cement, some vinyls and so much more! Flex Seal may not be compatible with all plastics, vinyls, or rubbers.
